Answer:
We get the value of Principal amount i.e initial investment = $61640
Step-by-step explanation:
Interest rate r = 3.59% or 0.0359
Compounded quarterly n = 4
Future Amount A = 117,300
Time t = 18 years
We need to find initial investment i,e Principal Amount P
The formula used is: 
Putting values and finding P

So, We get the value of Principal amount i.e initial investment = $61640
Answer:
h(x) = (x + 5)² - 18
Step-by-step explanation:
Given
h(x) = 7 + 10x + x² = x² + 10x + 7
To obtain vertex form, use the method of completing the square
add/ subtract ( half the coefficient of the x- term )² to x² + 10x
h(x) = x² + 2(5)x + 25 - 25 + 7
= (x + 5)² - 18 ← in vertex form
